Aliright ive been on my second cat now since 7000 miles and im wondering if its gonna get clogged up again. I know that i have a brand new cat on my car now but they didnt do anything to fix the problem they just gave me another bullshit part of the same kind thats just gonna go bad like the first one. I know there are a lot of threads about this but i couldnt find one to answer my question, "is it gonna clogg up again??" is anyone here on their 3rd or 4th cat by now? how can i fix this? Help me out here..... Effin chevy

 

Do you have anything done to the car? If you are running mad rich it will clog your cat. Have you had a PCM reflash to update to the newest code? I see you have the first year Cobalt SS.

 

the way i see it it has mainly been NY cobalts with cat problems. me u n darksun.
